LinkSys BEFSR41 V3 *REAL TESTED* WAN SPEED

Within some months my ISP will upgrade my connection from 10Mbit full duplex to 100Mbit full duplex

Is it possible for this router to handle this WAN speed? I know the WAN port is 100Mbit but it seems (all of these simple home routers) have problems with handeling such fast WAN-speeds because of their cpu wich is only about 200 till 300 mhz i heart... Does anyone here has an 100Mbit connection and can confirm this? Or maybe know if this router really can handle 100Mbit Half Duplex or even better 100Mbit Full Duplex of WAN-speed?
